I have some very clever little mice in my shed (you can read about them here). They have been taking great pleasure in toying with the conventional traps I set.
So, in response to their mocking, I have constructed 'The Mouse Arrest: mark 1'. I scoured the internet to find some fail-safe trap designs, but most of them kill the poor things slowly and horribly. The 'Mouse Arrest' (MAM01 for short) doesn't kill the cute critters, it simply traps them (so I can then feed them live to our pet eels ;-).
I based the MAM01 on ingenious plans by Manny Leger found here and will let you know who wins round 2. By the way, I'm just kidding about the eels.
